, the production of a simple, inexpensive, du-

rable and efiicient device for the purpose described.

To this end, my invention consists in the novel construction,combination and arran 'ement of parts herein shown and described, andmore particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like orcorresponding parts,Figure 1 is a plan view of the cover or closure; Fi2 is a sectional view taken on line 22 oi Fig. 1, also showing the topof the receptacle; Fig. 3 is a sectional view taken on line 22 of Fig.1, showing \he cover in place, and a vent sealed by producing a vacuumin the receptacle; Fig. 4C is.

also a section taken on line 22 of Fig. 1, showing a cover and part ofthe receptacle and a modified form of plug and expanding pin; Fig. 5 isa partial section of the cover and receptacle showin the plug with theexpanding pin removed; Fig. 6 1s a partial section of the cover andreceptacle showing a modified form of vent, and plug for the same; Fig.7 is a partial section of the same, showing theposition of the plug andexpanding pin when the air is exhausted from the receptacle; Fig. 8 is atop view of the preferred form of plug shown in Figs. 4 and 5; Fig. 9 isa section of the said plug taken on the line 9-9 of Fig. 8; Fig. 10 is across-section of same, taken on line l0-10 of Fig. 9; Fig. 11 shows acapped expanding pin in a plan view and section; Fig. 12 is across-section of a similar pin without the cap; Fig. 13 is a perspectiveview of my preferred formof plug; Fig. 14: shows a slightly modifiedform of plug and expanding pin; Fig. 15 shows the position of the samewhen the air within the receptacle has been exhausted; Fig. 16 .showsthe same form of pin, the vent in the cover being slightly taperedoutward at the top. Fig. 17 shows a cylindrical form of expanding plug.

Referring to the dra\ vings,1 is a portion of a jar or receptacle, and 2is a cover for the same. In the preferred form of cover, I provide avent or exhaust opening in the cover adapted to receive a plug similarto that shown in the drawings. This plug is preferably made of rubber orother similar elastic or expansible material, and consists of a head 3,a neck 4, and an extension 5, at the end of the neck opposite the head.If desired, the top or cover 2 may be recessed or countersunk around thevent,

as at 7, the bottom of the recess being preferably ground to give a goodseat for the head of the plug. To hermetically seal the juncture betweenthe receptacle 1 and the cover 2, when the air in the receptacle, isexhausted I preferably place a washer "6 made of rubber or othersuitable material on the cover 2, as shown, or on the top of the jar/When the receptacle is filled with the desired contents, the cover 2 isplaced in position with the plug inserted in the aperture, and the airexhausted. If the contents of the jar are heated or hot, the air ,withinthe receptacle will expand and a part will exhaust through the vent. Totake out the remaining air, any suitable mechanical means may beemployed, preferably any common form of air-pump. As the air isexhausted and a vacuum formed, the plug rises slightly and allows theair to escape, but drops back to its seat on the cover when the airattempts to return, acting similar to a check-valve.

To prevent the plug from being accidentally drawn out of the aperturewhile exhausting the air, I preferably provide a transverse extension 5on the base of the same. This transverse extension also holds the plugin place in the aperture, whenever desired, as in shipping or otherwise.\Vhen the air is exhausted, the plug is substantially in the positionshown in Fig. 3, the vacuum within the receptacle firmly retaining it insuch position, and the hermetically sealing washer 6 and the plugpreventing the passage of air back into the receptacle;

Figs. 8, 9, and 10 show a slightly modified form of plug than that shownin Figs. 2 and 3. In this form, a small opening or recess 8 extendspartially through the neck of the plug in a longitudinal direction, andis adapted to receive an expanding pin 9, preferably formedsubstantially as that shown out the cap. hen this pin is forced inrecess 8, as indicated in Fig. 4, it expands the neck 4 of the plug,preferably causing it to fill the clearance space between the neck ofthe plug and the walls of the vent 0 en- I ing through the cover. thusmore e ectively closing the vent. When the cap is provided 011 theexpanding pin, it tends to hold down the outer edge of the top 3 of theplug,

and -in this manner more efiectively seal the same, and protect the topof the plug from f accidental displacement.

In the preferred construction, the vent ap- I erture is slightly taperedoutward (see 10, f

Figs. 6 and 7) toward the bottom to form a frustum of a cone, in whichconstruction 2 the expanding pin will firmly lock'the plug in place,similar to a dove-tail lock.

the point of a knife or similar instrument under the head of the pin andlifting the same out of its seat, when by displacing the top of theflexible plug to one side air may be admltted, breaklng the vacuum, whenthe cover or top may be readily disconnected and removed from thereceptacle. The receptacles when placed on the market may; also have apaper label or the like, placed 1 adapted to extend across the aperturetoon the top of the cover, so as to cover the vent or recess 7, thusetlectively covering the vent opening, further sealing the same.

shown, they are preferably dipped in, or; smeared with glycerin, or asimilar article. I Having thus described my invention it is obvious thatvarious immaterial modifications may be made in the constructlon andarrangement of the same, hence I do not wish to be understood aslimiting myself to the exact form shown.
